P & A Campbell White Funnel pleasure steamer, Bristol

Image by brizzle born and bred
ON THE evening of February 15, 1919, the paddle steamer Albion locked in at Cumberland Basin. It was a Saturday evening and as the word spread, a couple of dozen onlookers gathered to see the battered ship, still armed, nonetheless painted the regulation grey of the Royal Navy.

Maybe the modest crowd raised a ragged cheer. Albion, her sister ships and their Bristolian crews were war heroes, and now the very first of them was back. It was yet another small sign that peace had actually returned.

Some of the onlookers would certainly have chatted about the very good times they had had on the ships, and would have looked forward to the summer time outings to come.

The initial of the P &amp A Campbell White Funnel pleasure steamers – &quotthe swans of the Avon&quot, one local writer called them – had returned home.

In all of the annals of Bristol in the Excellent War, the complete story of the Campbell paddle steamers remains relatively obscure.

It really is the exact same with Bristol’s merchant seamen generally merchant seamen didn’t tend to create their memoirs.

However in the case of the White Funnel fleet, the ships and their crews, who were nearly all Bristol men, did vital war service.

A single was a transport at Gallipoli and some of the others had encounters with enemy submarines, but for the most component they had been utilized as minesweepers.

This was not just thankless work, it was hazardous. In statistical terms, you stood a better opportunity of survival in the Very first Planet War as a soldier in the trenches than you did operating on minesweepers.

It was to the immense credit of the Bristol steamers that only two out of 13 had been lost.

The casualty figures had been impressive, as well. Although some men have been lost, there do not seem to have been any casualties from the Bristolians among them.

These reasonably little losses says a lot for their professionalism and knowledge, and the high quality of their mostly Clyde-constructed ships.

Before the war Campbell’s steamers had been a well-known feature of Bristol’s summer season.

Folks would dress in their Sunday ideal for an outing down the Avon and into the Channel on weekends and Bank Holidays, heading off for a day out in Lynmouth, Clovelly, Minehead or Ilfracombe.

Simply because of all these happy memories, it came as a shock when the ships had been requisitioned by the Admiralty to turn into minesweepers. By the middle of the war the Navy had taken all 13 of them.

The Navy brass knew what they had been doing. Paddle steamers operating as pleasure boats had been highly manoeuvrable but, more importantly, simply because they operated in coastal waters they had shallow draughts.

Enemy mines were generally laid to hit reduced hulls a pleasure boat stood a fighting possibility of being in a position to sail proper more than one particular unscathed.

The very same applied with submarine torpedoes. &quotThey constantly went nicely beneath our bottom, thank you,&quot mentioned an officer of the Devonia following the war.

The very first to leave have been Devonia and Brighton Queen, headed for Devonport in September 1914.

Most of the other folks have been taken, a single by 1, to G.K. Stothert’s dockyard at Hotwells, and fitted out for war painted grey and armed for duty with machine guns and 12-pounders.

A single by 1, they were taken down the Avon by guys from Bristol, Pill, Shirehampton and Avonmouth now acting under Admiralty orders, to take station about Britain’s coast.

Devonia, Brighton Queen, Cambria, Westward Ho!, Glen Avon and Lady Ismay remained together as a flotilla through the war, based at Grimsby, and later on the Tyne.

An account of 1 of their adventures written by one particular of the males on one more boat in the group, the yacht Saggita, offers a vivid description of their hazardous function. In April 1915 Westward Ho! and the Sagitta had been mine-hunting in the North Sea:

Soon soon after sweeping began there was a loud explosion in the sweep in between our companion the Westward Ho!, and us, and a mound of water was hurled into the air. Two mines had burst in our sweep. A handful of seconds later an additional bobbed up, cut from its moorings by our sweep wire. The sound of the explosion was followed by full silence. All the ships had immediately stopped, and lay rolling slightly to the disturbance brought on by the bursting mines.

Any harm carried out? No, all the ships have been there. &quotWe will pick up that mine&quot stated the Commander. Our end of the wire was &quotslipped,&quot or let go, a boat was lowered, and he and the C/O, with two hands went off. Of course, strictly speaking, the C/O ought to not have gone. His place was on board, particularly as mines had been about, but the immediate danger in the boat attracted him — he was that sort of man — and he would not hear of any individual else going. Off went the boat, while the rest of us looked on, and wondered what would happen. The boat circled round the black, sinister hunting mine, bobbing about so innocently in the sea, and then the C/O jumped into the water, swam up to the mine, and reduce the two outdoors wires major to the detonator.

This the Commander thought need to make it secure, even though he was not confident. The mine was then towed alongside, a derrick swung out, the mine hooked on, hoisted out, and lowered on deck right after the detonator had been pulled out. We breathed freely as soon as more. It was certainly safe now that the detonator was out.

The next job was to pick it to pieces, and this was successfully completed. It was found to be surprisingly properly produced, and all the inside parts were hugely completed. In truth they could hardly have been bettered if intended for an exhibition. Contemplating that it was destined in the ordinary way to be blown to bits it appears strange that so considerably care need to have been bestowed on polishing and machining the performs. 1 of the parts bore a quite current date, proving that the mines had not been laid extended. In reality in one way and an additional really a lot of data was gleaned from this mine, which was sent to the Admiralty when we returned to harbour.

The two ships to be lost in the war have been in the Grimsby Flotilla.

On October six, 1915, Brighton Queen hit a mine off the Belgian coast and sank speedily, with the loss of seven men (Bristol’s neighborhood press, in the way of regional press then and now, noted that none of them have been from Bristol).

Two months later the Lady Ismay struck a mine in the Thames Estuary and went down in two minutes with the loss of 19 men.

The very same number, nevertheless, were saved by boats from the ships accompanying her.

This episode was very renowned at the time for the action of Chief Petty Officer Walter Carter of Dartmoor Street, Bedminster. He was commended by the Admiralty for trying to save another man by dragging him onto a life raft and giving artificial respiration.

The 4 remaining Campbell ships at Grimsby had been later moved to the Tyne exactly where they saw out the rest of the war undertaking similar perform.

Six of the other steamers had been sent to the Clyde and spent the war around the coast of Scotland. One, the Glen Usk, was present when the German fleet surrendered at Scapa Flow on November 21 1918.

Albion and Ravenswood went to Dover and with the Grimsby flotilla they took part in clearing mines prior to the Zeebrugge Raid.

Their crewmen had been delighted to discover out soon after the war that they had been described in an official German report as &quotlight cruisers&quot.

They were beneath heavy fire, and Albion also survived a German air attack. She was not so lucky two years later when a little bomb hit her stern and two officers had been killed.

The Waverley went to Portland and the Glen Rosa to Cardiff, where she swept the Bristol Channel for mines. Each had been sent to the Thames later in the war.

The Barry had the most exciting war of all of them. Known as up in 1915 she first took 400 prisoners-of-war to Dublin to be moved to a camp in Ireland. She was then sent to the Mediterranean where she spent six weeks ferrying troops, ammunition and supplies to the Gallipoli beaches, nearly usually below artillery fire.

When the campaign was abandoned it was the Barry that was the very last to leave, evacuating the guys of the rearguard from Suvla Bay.

Barry saw out the rest of the war in the Mediterranean ferrying troops and supplies around.

&quotThey went forth,&quot said a newspaper reporter in 1919 of the 11 which 1 by a single had returned to the city docks and have been now getting painted white when much more, &quoton the wonderful adventure and braved, oft-instances, the fury of heavy gales on operate for which they were definitely by no means intended. And in spite of all the dangers, they came back. When they first went away, the steamers have been manned totally by neighborhood males, and though two of the White Funnels had been lost, other vessels of the exact same fleet were capable to rescue all the Bristol men aboard.&quot

The Reverse Of The Carpathia Medal For The Rescue Of The Survivors Of The Titanic Disaster April 1912.

Image by Jimmy Huge Potatoes
RMS Carpathia was a Cunard Line transatlantic passenger steamship constructed by Swan Hunter &amp Wigham Richardson. Carpathia produced her maiden voyage in 1903 and became famous for rescuing the survivors of RMS Titanic after the latter ship hit an iceberg and sank on 15 April 1912. Carpathia herself was sunk in the Atlantic on 17 July 1918 during the 1st Globe War, following becoming torpedoed by an Imperial German Navy U-boat.

History Building and early service.
RMS Carpathia was built by Swan Hunter &amp Wigham Richardson at their Newcastle upon Tyne, England shipyard. She was launched on six August 1902 and underwent her sea trials between 22 and 25 April 1903. Carpathia displaced eight,600 long tons (eight,700 t) and was 541 ft (165 m) extended and 64 ft 6 in (19.66 m) breadth.

Carpathia made her maiden voyage on 5 Could 1903 from Liverpool, England, to Boston, USA, and ran services amongst New York City, Gibraltar, Genova, Naples, Trieste and Fiume.

Titanic disaster.
A.H. Rostron, R.D., R.N.R., as master of RMS CarpathiaCarpathia was sailing from New York City to Fiume, Austria-Hungary (now Rijeka, Croatia) on the night of Sunday, 14 April 1912. Amongst her passengers were the American painters Colin Campbell Cooper and his wife Emma, journalist Lewis P. Skidmore, photographer Dr. Francis H. Blackmarr, and Charles H. Marshall, whose 3 nieces had been travelling aboard Titanic.

Carpathia’s wireless operator, Harold Cottam, had missed earlier messages from Titanic, as he was on the bridge at the time. He then received messages from Cape Race, Newfoundland, stating they had private site visitors for Titanic. He believed he would be helpful and at 12:11 am on 15 April sent a message to Titanic stating that Cape Race had visitors for them. In reply he received Titanic’s distress signal. Cottam awakened Captain Arthur Henry Rostron who right away set a course at maximum speed (17 kn (20 mph 31 km/h)) to Titanic’s last identified position, around 58 mi (93 km) away. Rostron ordered the ship’s heating and hot water cut off in order to make as a lot steam as achievable obtainable for the engines. At full speed it took the Carpathia four hours to attain Titanic, even though Titanic only stayed afloat for two hours and sank prior to Carpathia arrived. At 4:00 am, Carpathia arrived at the scene, after working her way by means of hazardous ice fields, and took on 705 survivors of the disaster from Titanic’s lifeboats

For their rescue function, the crew of Carpathia were awarded medals by the survivors. Crew members had been awarded bronze medals, officers silver, and Captain Rostron a silver cup and a gold medal, presented by Margaret Brown. Rostron was knighted by King George V, was later a guest of President Taft at the White House, exactly where he was presented with a Congressional Gold Medal, the highest honour the United States Congress could confer upon him.

Service in World War I
Throughout the Very first World War, Carpathia was utilised to transfer Canadian and American troops to Europe. She was used as a troopship by the Canadian Expeditionary Force. At least some of her voyages were in convoy, sailing from New York via Halifax to Liverpool and Glasgow. Amongst her passengers throughout the war years was Frank Buckles, who went on to grow to be the last surviving American veteran of the war.

Sinking.
On 15 July 1918, Carpathia departed Liverpool in a convoy bound for Boston. On the summer morning of 17 July she was torpedoed, at 9:15, in the Celtic Sea by the Imperial German Navy submarine U-55. Of 3 torpedoes fired at the ship, one particular impacted the port side whilst the other penetrated the engine space, killing two firemen and three trimmers. As Carpathia started to settle by the head and list to port, Captain William Prothero gave the order to abandon ship. All 57 passengers (36 saloon class and 21 steerage) and 218 surviving crew members boarded the lifeboats as the vessel sank. U-55 surfaced and fired a third torpedo into the ship and was approaching the lifeboats when the Azalea-class sloop HMS Snowdrop arrived on the scene and drove away the submarine with gunfire prior to choosing up the survivors from Carpathia.

Carpathia sank at 11:00 AM at a position recorded by Snowdrop as 49.25 N 10.25 W, about 120 mi (190 km) west of Fastnet.

Locating and salvage operates.
On 9 September 1999, the Reuters and AP wire solutions reported that Argosy International Ltd., headed by Graham Jessop, son of the undersea explorer Keith Jessop, and sponsored by the National Underwater and Marine Agency, had discovered Carpathia’s wreck in 600 ft (180 m) of water, 185 mi (298 km) west of Land’s End. Bad weather forced his ship to abandon the position just before Jessop could verify the discovery making use of underwater cameras. However, when he later returned to the place the wreck proved to be not that of Carpathia but that of the Hamburg-America Line’s Isis, sunk on eight November 1936.

In 2000, the American author and diver Clive Cussler announced that his organization, NUMA, had discovered the accurate wreck of Carpathia in the spring of that year, at a depth of 500 ft (150 m). Following the submarine attack Carpathia landed upright on the seabed. NUMA gave the approximate place of the wreck as 120 mi (190 km) west of Fastnet, Ireland.

The vessel is presently owned by Premier Exhibitions Inc., formerly RMS Titanic Inc., which plans to recover objects from the wreck. The exact same company owns the salvor-in-possession rights of Titanic, from which numerous artefacts have been recovered and are on show in worldwide exhibitions.

One Earth: Aerial View, Phoenix Driveway

Image by cobalt123
For the 1 Earth group project, my picture selected for the group pool. This is taken in my driveway in late afternoon. The robust light approaching sunset casts magical dark shadows. The image appears to me like what I’ve observed from traveling on planes more than the vast unpopulated areas of the Southwest. Doesn’t it appear like there is a river branching beneath, with dark shadows reaching down from the nearest clouds to Earth’s surface and the highest altitude clouds moving along with a lot smoother blobs of shadow?

Truly, the dark shadows at the bottom of this image are from the guidelines of leaves on the nearby privet hedge. The extended &quotlog&quot or pipeline in the upper central focus is a rusty nail. If I had not taken this photo and looked at it in Photoshop, I would not have realized there was a NAIL in my driveway that necessary to be picked up!

Remarkable what you discover from searching straight down, at times. The preceeding photos are also from the driveway and out to the busy street in front of my house in central Phoenix. There is more pavement and asphalt here in this neighborhood than any other ground covering. This is also why it gets so exceptionally hot in metro Arizona and the heat stays, held like a warming plate does, in this pavement. Sometimes you can feel waves of heat increasing up through the ground as you stroll. I can’t wait for &quotwinter&quot to come!

SAM S-75 Dvina. ЗРК С-75 “Двина”

Image by Peer.Gynt
Saint-Petersburg. Artillery Museum.

The S-75 Dvina (Russian: С-75 NATO reporting name SA-2 Guideline) is a Soviet-developed, higher-altitude, command guided, surface-to-air missile (SAM). Because its 1st deployment in 1957 it has turn out to be the most broadly-deployed air defense missile in history. It scored the initial destruction of an enemy aircraft by a SAM, shooting down a Taiwanese Martin RB-57D Canberra over China, on October 7, 1959 by hitting it with 3 V-750 (1D) missiles at an altitude of 20 km (65,600 ft). The achievement was attributed to Chinese fighters at the time in order to keep the S-75 system secret.
This system initial gained international fame when an S-75 battery, employing the newer, longer-variety and larger-altitude V-750VN (13D) missile shot down the U-two of Francis Gary Powers overflying the Soviet Union on Might 1, 1960.[3] The program was also deployed in Cuba throughout the Cuban Missile Crisis, exactly where on October 27, 1962, it shot down the U-two flown by Rudolf Anderson, nearly precipitating nuclear war.[4] North Vietnamese forces utilized the S-75 extensively in the course of the Vietnam War to defend Hanoi and Haiphong. It has also been locally produced in the People’s Republic of China making use of the names HQ-1 and HQ-two. Other nations have produced so several local variants combining portions of the S-75 program with both indigenously-developed components or third-celebration systems that it has become practically impossible to discover a pure S-75 method nowadays,
Improvement
In the early 1950s, the United States Air Force rapidly accelerated its development of extended-variety jet bombers carrying nuclear weapons. The USAF plan led to the deployment of Boeing B-47 Stratojet supported by aerial refueling aircraft to extend its variety deep into the Soviet Union. The USAF quickly followed the B-47 with the improvement of the Boeing B-52 Stratofortress, which had greater range and payload than the B-47. The range, speed, and payload of these U.S. bombers posed a significant threat to the Soviet Union in the occasion of a war between the two nations.
onsequently, the Soviets initiated the development of improved air defense systems. Although the Soviet Air Defence Forces had massive numbers of anti-aircraft artillery (AAA), which includes radar-directed batteries, the limitations of guns versus higher-altitude jet bombers was obvious. Therefore, the Soviet Air Defense Forces began the improvement of missile systems to replace the World War II-vintage gun defenses.
In 1953, KB-2 began the development of what became the S-75 beneath the direction of Pyotr Grushin. This system focused on generating a missile which could bring down a big, non-maneuvering, higher-altitude aircraft. As such it did not require to be highly maneuverable, merely quick and able to resist aircraft counter-measures. For such a pioneering technique, improvement proceeded swiftly, and testing started a couple of years later. In 1957, the wider public very first became aware of the S-75 when the missile was shown at that year’s May Day parade in Moscow.
Initial deployment
Wide-scale deployment started in 1957, with various upgrades following over the next couple of years. The S-75 was by no means meant to replace the S-25 Berkut surface-to-air missile internet sites about Moscow, but it did replace high-altitude anti-aircraft guns, such as the 130 mm KS-30 and 100 mm KS-19. Amongst mid-1958 and 1964, U.S. intelligence assets located much more than 600 S-75 websites in the USSR. These internet sites tended to cluster around population centers, industrial complexes, and government control centers. A ring of internet sites was also positioned about likely bomber routes into the Soviet heartland. By the mid-1960s, the Soviet Union had ended the deployment of the S-75 with maybe 1,000 operational websites.
In addition to the Soviet Union, several S-75 batteries have been deployed throughout the 1960s in East Germany to defend Soviet forces stationed in that country. Later the system was sold to most Warsaw Pact countries and was supplied to China, North Korea, and ultimately, North Vietnam.
Employment
While the shooting down of Francis Gary Powers’ U-2 in 1960 is the 1st publicized success for the S-75, the first aircraft really shot down by the S-75 was a Taiwanese Martin RB-57D Canberra higher-altitude reconnaissance aircraft. In this case, the aircraft was hit by a Chinese-operated S-75 web site near Beijing on October 7, 1959. More than the next few years, the Taiwanese ROCAF would drop a quantity of aircraft to the S-75: both RB-57s and a variety of drones. On Might 1, 1960, Gary Powers’s U-two was shot down even though flying over the testing site close to Sverdlovsk, although it is thought to have taken 14 missiles to hit his higher-flying plane. That action led to the U-two Crisis of 1960. In addition, Chinese S-75s downed five ROCAF-piloted U-2s based in Taiwan.[five]
During the Cuban Missile Crisis, a U-two piloted by USAF Key Rudolf Anderson was shot down more than Cuba by an S-75 in October 1962.[six]
In 1965, North Vietnam asked for some help against American airpower, for their own air-defense system lacked the ability to shoot down aircraft flying at high altitude. Right after some discussion it was agreed to supply the PAVN with the S-75. The choice was not produced lightly, due to the fact it drastically elevated the chances that a single would fall into US hands for study. Web site preparation began early in the year, and the US detected the plan almost quickly on April 5, 1965. Even though military planners pressed for the websites to be attacked just before they could grow to be operational, their political leaders refused, fearing that Soviet technical staff may possibly be killed.
On July 24, 1965, a USAF F-4C aircraft was shot down by an SA-two.[7] 3 days later, the US responded with Operation Iron Hand to attack the other websites before they could grow to be operational. Most of the S-75 had been deployed about the Hanoi-Haiphong area and have been off-limits to attack (as have been local airfields) for political causes. President Lyndon Johnson announced on public Television that a single of the other internet sites would be attacked the next week. The Vietnamese removed the missiles and replaced them with decoys, whilst moving each and every obtainable anti-aircraft gun into the strategy routes. The tactic worked, causing heavy American casualties.
The missile technique was used extensively all through the globe, especially in the Middle East, where Egypt and Syria utilized them to defend against the Israeli Air Force, with the air defense net accounting for the majority of the downed Israeli aircraft. The final apparent accomplishment appears to have occurred during the War in Abkhazia (1992–1993), when Georgian missiles shot down a Russian Sukhoi Su-27 fighter close to Gudauta on March 19, 1993.
Countermeasures and counter-countermeasures
Among 1965 and 1966, the US delivered a quantity of options to the S-75 difficulty. The Navy soon had the Shrike missile in service and mounted their 1st offensive strike on a web site in October 1965. The Air Force responded by fitting B-66 bombers with potent jammers (that blinded the early warning radars) and by establishing smaller sized jamming pods for fighters (that denied range data to the radars). Later developments included the Wild Weasel aircraft, which have been fitted with anti-radiation air-to-surface missile systems produced to residence in on the radar from the threat. This freed them to shoot the websites with Shrikes of their personal.
The Soviets and Vietnamese, however, were able to adapt to some of these techniques. The USSR upgraded the radar many occasions to boost ECM (electronic counter measure) resistance. They also introduced a passive guidance mode, whereby the missile could lock on the jammer itself. This had an added benefit, simply because the radar had to be turned off, which prevented Shrikes from becoming fired. Additionally, some new tactics have been developed to combat the Shrike. A single of them was to point the radar to the side and then turn it off briefly. Given that the Shrike was a relatively primitive anti-radiation missile, it would follow the beam away from the radar and then basically crash when it lost the signal (right after the radar was turned off). One more was a &quotfalse launch&quot in which the tracking radar was turned on, but the missiles had been not truly fired. This permitted the missile crew to see if the target was equipped with a Shrike. If the aircraft fired one, the Shrike could be neutralized with the side-pointing technique without sacrificing any S-75s.
Despite these advances, the US was able to come up with efficient ECM packages for the B-52E models. These planes had been in a position to fly raids against Hanoi with comparatively few losses (though nonetheless considerable adequate to lead to some concern see Operation Linebacker II).
Replacement systems
Soviet Air Defence Forces started to replace the S-75 with the vastly superior SA-10 and SA-12 systems in the 1980s. Nowadays only a couple of hundred, if any, of the 4,600 missiles are nonetheless in Russian service, even although they underwent a modernization program as late as 1993.[citation necessary]
The S-75 remains in widespread service all through the world, with some level of operational capability in 35 nations. Vietnam and Egypt are tied for the biggest deployments at 280 missiles every, although North Korea has 270, and Poland has 240. The Chinese also deploy the HQ-two, an upgrade of the S-75, in fairly large numbers.
Soviet doctrinal organization
The Soviet Union utilised a relatively normal organizational structure for S-75 units. Other countries that have employed the S-75 might have modified this structure. Generally, the S-75 is organized into a regimental structure with 3 subordinate battalions. The regimental headquarters will manage the early-warning radars and coordinate battalion actions. The battalions will contain a number of batteries with their linked acquisition and targeting radars.
Site layout
Each and every battalion will usually have six, semi-fixed, single-rail launchers for their V-750 missiles positioned around 60 to 100 m (200 to 330 ft) apart from each and every other in a hexagonal &quotflower&quot pattern, with radars and guidance systems placed in the center. It was this special &quotflower&quot shape that led to the internet sites becoming simply recognizable in reconnaissance photographs. Usually an additional six missiles are stored on tractor-trailers close to the center of the site.
An instance of a web site can be observed right here just to the west of the junction to Bosra on the M5 motorway in Syria, south of Damascus. This place covers the borders with each Israel and Jordan, so it is of strategic value.

The V-750 is a two-stage missile consisting of a strong-fuel booster and a storable liquid-fuel upper stage, which burns red fuming nitric acid as the oxidizer and kerosene as the fuel. The booster fires for about 4–5 seconds and the principal engine for about 22 seconds, by which time the missile is traveling at about Mach three. The booster mounts 4 huge, cropped-delta wing fins that have small handle surfaces in their trailing edges to manage roll. The upper stage has smaller cropped-deltas near the middle of the airframe, with a smaller set of manage surfaces at the intense rear and (in most models) a lot smaller sized fins on the nose.
The missiles are guided making use of radio control signals (sent on 1 of 3 channels) from the guidance computers at the web site. The earlier S-75 models received their commands through two sets of four small antennas in front of the forward fins, although the D model and later models used 4 considerably larger strip antennas operating in between the forward and middle fins. The guidance technique at an S-75 internet site can deal with only one target at a time, but it can direct 3 missiles against it. Added missiles could be fired against the identical target soon after one particular or far more missiles of the very first salvo had completed their run, freeing the radio channel.
The missile typically mounts a 195 kg (430 lb) fragmentation warhead, with proximity, speak to, and command fusing. The warhead has a lethal radius of about 65 m (213 ft) at decrease altitudes, but at higher altitudes the thinner atmosphere allows for a wider radius of up to 250 m (820 ft). The missile itself is correct to about 75 m (246 ft), which explains why two were typically fired in a salvo. One version, the SA-2E, mounted a 295 kg (650 lb) nuclear warhead of an estimated 15 Kiloton yield or a conventional warhead of comparable weight.
Standard variety for the missile is about 45 km (28 mi), with a maximum altitude about 20,000 m (66,000 ft). The radar and guidance technique imposed a relatively lengthy short-variety cutoff of about 500 to 1,000 m (1,600 to 3,300 ft), making them fairly safe for engagements at low level.

Brick Breeden Fieldhouse sign on the campus of Montana State University in Bozeman, Montana.

Nearby architect George Carsley and nationally-recognized architect Cass Gilbert created the MSU master campus plan in 1917. But anticipating sudden growth after Globe War II, a master strategy re-design and style occurred in 1940 that clustered buildings a lot closer with each other. Campus growth expanded beyond the 1917 and 1940 plans, nonetheless, leading to more haphazard placement of buildings than the symmetry envisioned by the 1917 strategy. Brick Breeden Fieldhouse is standard of the asymmetric development of the campus.

University President Roland Renne intended to construct an indoor football arena. He approached regional architect Oswald Berg, Jr., to style it. Such a large structure, even so, proved not possible to finance, so a fieldhouse was constructed as an alternative. Made to be a well being and physical education center, the original January1956 style was a low cylindrical creating topped with a dome with curving one-story office wings extending north and south. The plan was to construct the center structure first, and the wings later. Nevertheless, only the northern wing was constructed – and it was significantly altered from the original plan.

Brick Breeden Fieldhouse was developed by omnipresent local architect Fred F. Willson and nearby architect Oswald Berg Jr. The .six million ( million in 2013 inflation-adjusted dollars) structure was dedicated in December 1957 and opened in 1958. The creating was named after Brick Breeden, who played on MSU’s &quotGolden Bobcats&quot 1928 national championship basketball team and who later was head basketball coach and athletic director at the college.

The central structure consists of a steel frame in pink-tinted concrete masonry, even though portions of the building are clad in brick. The pattern is stacked bond. The foundation is concrete foundation and the roof a membrane. Exterior bays are defined by deep concrete ribs which taper in a curve outward at the top. Vertically oriented, fixed windows with aluminum mullions connect the exterior wall to the dome. These windows lean outward toward a metal circumferential fascia, giving the developing the appearance of flaring. There are often spaced low vents on the domed roof. Interior doors are metal, except as noted beneath.

As constructed, the original entry was on the west side. It was a rectangular structure forming a two story-high foyer with a slightly upward-curved roof. A steeply-sloped berm led down to the west. Sidewalks approached from the northeast. Access was via seven-riser concrete actions heading south, which led up to a little concrete plaza one particular floor up. The west wall here was in two components: The northern section was about two and a half bays wide, and created of floor-to-ceiling pink concrete masonry three stories higher. A 3-bay wide, floor-to-ceiling glass curtain wall (also three stories high) formed the south section of this part of the west wall. 3 double glass doors offered entry to what was the primary level of the fieldhouse by means of a single-story foyer. A 17-riser concrete staircase heading south led up to yet another, larger plaza 1 floor up. A glass curtain wall 15 bays wide and two stories higher formed the major entrance. On the left (northern) finish of this wall were two sets of glass double doors. On the proper (south) finish have been seven sets of glass double-doors which gave entry to the second level of the fieldhouse through a two-story foyer. (This was later reduced to six double-doors.) Except for the transoms over every single double-door, all the glass right here was frosted light blue.

A single-story structure extended north from the foyer structure. This was constructed at the primary level of the fieldhouse, which meant it projected out more than empty space on the initial sub-level of the fieldhouse. Beneath it was concrete-floored open air space. A roof extended even additional to the north to continued to cover this space. Paralleling the sidewalk was a small access road that led to this space, forming a curved driveway in front of it. The space served as sort of pavilion for guests debarking from automobiles in the driveway. Significantly later, the back component of this pavilion was enclosed and turned into offices.

Initially, a wing (constructed in 1957) projected out from the fieldhouse at the man level. Three sets of five-riser concrete stairs led up to this wing, which was clad in pink concrete masonry. The first story of the north face of this two-story wing was glass, six bays wide. The middle two bays had glass double-doors. Initially, a space about 25 feet wide separate the north wing from the projecting pavilion extension of the foyer. In the 1970s, this was filled with a structure that was flush with the north face of the north wing. (The pavilion extension went previous the façade of the north wing by about 15 to 20 feet.) The first floor of this fill-in structure was clad in pink concrete masonry, but the second floor was floor-to-ceiling windows. A third floor with a steeply pitched (60 degrees) roof was clad in grey vinyl siding. The west side of this fill-in structure was about 5 feet greater than the pavilion wing, so that if formed a type of dormer via which windows gave light into the offices on the third floor. The east side of this fill-in structure was about 3 feet lower than the cornice line of the north wing, and transom-like windows in the north wing gave light to the second floor offices inside.

To the west of the north entrance, a rectangular service wing was added. The rear third of it against the fieldhouse) was two stories high, while the northern third was a single story higher. Extending from the northwest corner was a covered walkway connecting the fieldhouse to Shroyer Fitness center. The north-facing northeast corner had a garage door in it. The east face had five tiny square windows and two metal doors set into it. This wing was almost certainly built at the same time as the Hosaeus Fitness Complicated in 1972-1973/

The east façade of the fieldhouse was also changed. This curved creating wraps about the east and southeast façades. On the north end is a plain brick single-story structure with a garage door in the southern third of it. A plain aluminum canopy supported by steel posts covers three service regions. The exterior wall of this service area is concrete block. Along the southeast is a two-story service constructing whose ground floor is set halfway under grade. Modest square windows on the second floor offer light and below-grade metal doors offer entry.

The south façade of the creating was initially blank like the east and southeast. Right now, it is the fieldhouse’s primary entrance. A huge parking lot exists on this side of the creating. The entrance is set at the second level of the fieldhouse, and concrete stairs of 11 and 13 risers lead up to it. The new major entry faces slightly south-southwest, and is four bays wide. The two leftmost bays consist of two sets of glass double-doors with a double-high transom light overhead. The bay second from right has a single set of glass double-doors set left. Emblazoned on the fascia overhead is the word &quotTICKETS&quot. Upon getting into this door, the visitor will see a will-contact ticket booth immediately to the right (behind what would have been the other set of glass double-doors). The rightmost bay is brick to about 3 feet, and a ticket window above that. It, too, has a fascia emblazoned with &quotTICKETS&quot above it.

The third level of the fieldhouse on the south side has been extended outward slightly. A glass curtain wall echoes the curtain wall on the west façade. A sharply pitched gable-like structure juts out of the two leftmost bays. Beneath a moderate eave is a floor-to-ceiling glass wall framed in metal.

To the west of the new major entrance is a tiny, 1-story structure. A berm rises up to the windowsills. The roof is flat, and the façade is brown concrete masonry. A metal double-entry door is on its left.

A curving thin brick interior wall pierced by doors separates the entry areas from the arena inside the fieldhouse. Bleachers rise almost to the window beneath the dome’s eaves, and the steel trusses of the interior and dome are exposed. The building can seat 9,500.

The north wing addition in structure was created by in 1969 by Berg-Grabow and Partners (the successor to Willson and Berg). It is probably that the modest office jutting off the south entrance was built at this time as effectively. The northwestern fill-in structure and covered walkway to Shroyer Gym have been probably constructed in 1973.

As constructed, the primary floor of the arena was dirt. A wooden court was assembled every single time a basketball game was played there, and wooden boardwalks led from the entryways to the stands. The dirt floor was covered with a synthetic polyurethane &quotTartan&quot floor and retractable bleachers installed in 1980.

The new main entrance was constructed in 1996, and completed in 1998. The .two million renovation also added elevators and handicapped accessible concessions and restrooms, replaced the original bleacher seats, added a fire suppression program, added seismic reinforcements, and upgraded the HVAC method. Offices and lockerrooms inside the structure were also renovated. The east-southeast wraparound addition added in 2007.

Brick Breeden Fieldhouse no longer retains adequate design and style integrity for it to be listed on the National Register of Historic Locations.

At the time of its building, Brick Breeden Fieldhouse was the biggest unsupported wooden structure in the world. As of 2013, it is the third-biggest, behind the Walkup Skydome in Flagstaff, Arizona, and the Tacoma Dome in Tacoma, Washington.

The structure was initially known as MSC Fieldhouse. It was renamed for Brick Breeden in 1981. The arena inside the fieldhouse was named for Max Worthington (a colleague of Breeden’s on the &quotGolden Bobcats&quot basketball team) in 1985.

Looking east at the west side of Brick Breeden Fieldhouse on the campus of Montana State University in Bozeman, Montana. This is the original main entrance to the fieldhouse, but these days serves as an exit only.

Local architect George Carsley and nationally-identified architect Cass Gilbert created the MSU master campus plan in 1917. But anticipating sudden development right after Planet War II, a master strategy re-design and style occurred in 1940 that clustered buildings a lot closer together. Campus growth expanded beyond the 1917 and 1940 plans, nonetheless, major to far more haphazard placement of buildings than the symmetry envisioned by the 1917 plan. Brick Breeden Fieldhouse is typical of the asymmetric development of the campus.

University President Roland Renne intended to develop an indoor football arena. He approached local architect Oswald Berg, Jr., to design it. Such a big structure, nonetheless, proved not possible to finance, so a fieldhouse was constructed instead. Made to be a wellness and physical education center, the original January1956 design was a low cylindrical developing topped with a dome with curving one particular-story workplace wings extending north and south. The program was to construct the center structure first, and the wings later. However, only the northern wing was constructed – and it was significantly altered from the original program.

Brick Breeden Fieldhouse was created by omnipresent neighborhood architect Fred F. Willson and neighborhood architect Oswald Berg Jr. The .six million ( million in 2013 inflation-adjusted dollars) structure was devoted in December 1957 and opened in 1958. The developing was named right after Brick Breeden, who played on MSU’s &quotGolden Bobcats&quot 1928 national championship basketball team and who later was head basketball coach and athletic director at the college.

The central structure consists of a steel frame in pink-tinted concrete masonry, despite the fact that portions of the building are clad in brick. The pattern is stacked bond. The foundation is concrete foundation and the roof a membrane. Exterior bays are defined by deep concrete ribs which taper in a curve outward at the leading. Vertically oriented, fixed windows with aluminum mullions connect the exterior wall to the dome. These windows lean outward toward a metal circumferential fascia, giving the creating the appearance of flaring. There are often spaced low vents on the domed roof. Interior doors are metal, except as noted below.

As constructed, the original entry was on the west side. It was a rectangular structure forming a two story-high foyer with a slightly upward-curved roof. A steeply-sloped berm led down to the west. Sidewalks approached from the northeast. Access was via seven-riser concrete methods heading south, which led up to a modest concrete plaza 1 floor up. The west wall here was in two parts: The northern section was about two and a half bays wide, and produced of floor-to-ceiling pink concrete masonry 3 stories high. A 3-bay wide, floor-to-ceiling glass curtain wall (also three stories high) formed the south section of this part of the west wall. Three double glass doors offered entry to what was the principal level of the fieldhouse via a single-story foyer. A 17-riser concrete staircase heading south led up to an additional, bigger plaza a single floor up. A glass curtain wall 15 bays wide and two stories higher formed the principal entrance. On the left (northern) finish of this wall were two sets of glass double doors. On the appropriate (south) end were seven sets of glass double-doors which gave entry to the second level of the fieldhouse through a two-story foyer. (This was later decreased to six double-doors.) Except for the transoms over each and every double-door, all the glass here was frosted light blue.

A single-story structure extended north from the foyer structure. This was built at the main level of the fieldhouse, which meant it projected out more than empty space on the very first sub-level of the fieldhouse. Beneath it was concrete-floored open air space. A roof extended even further to the north to continued to cover this space. Paralleling the sidewalk was a little access road that led to this space, forming a curved driveway in front of it. The space served as sort of pavilion for guests debarking from automobiles in the driveway. Considerably later, the back portion of this pavilion was enclosed and turned into offices.

Originally, a wing (constructed in 1957) projected out from the fieldhouse at the man level. 3 sets of five-riser concrete stairs led up to this wing, which was clad in pink concrete masonry. The very first story of the north face of this two-story wing was glass, six bays wide. The middle two bays had glass double-doors. Originally, a space about 25 feet wide separate the north wing from the projecting pavilion extension of the foyer. In the 1970s, this was filled with a structure that was flush with the north face of the north wing. (The pavilion extension went previous the façade of the north wing by about 15 to 20 feet.) The 1st floor of this fill-in structure was clad in pink concrete masonry, but the second floor was floor-to-ceiling windows. A third floor with a steeply pitched (60 degrees) roof was clad in grey vinyl siding. The west side of this fill-in structure was about 5 feet larger than the pavilion wing, so that if formed a kind of dormer through which windows gave light into the offices on the third floor. The east side of this fill-in structure was about three feet lower than the cornice line of the north wing, and transom-like windows in the north wing gave light to the second floor offices inside.

To the west of the north entrance, a rectangular service wing was added. The rear third of it against the fieldhouse) was two stories high, although the northern third was a single story higher. Extending from the northwest corner was a covered walkway connecting the fieldhouse to Shroyer Gym. The north-facing northeast corner had a garage door in it. The east face had five little square windows and two metal doors set into it. This wing was possibly constructed at the same time as the Hosaeus Fitness Complex in 1972-1973/

The east façade of the fieldhouse was also changed. This curved developing wraps about the east and southeast façades. On the north end is a plain brick single-story structure with a garage door in the southern third of it. A plain aluminum canopy supported by steel posts covers 3 service places. The exterior wall of this service region is concrete block. Along the southeast is a two-story service building whose ground floor is set halfway beneath grade. Modest square windows on the second floor provide light and below-grade metal doors provide entry.

The south façade of the building was initially blank like the east and southeast. Nowadays, it is the fieldhouse’s major entrance. A huge parking lot exists on this side of the building. The entrance is set at the second level of the fieldhouse, and concrete stairs of 11 and 13 risers lead up to it. The new major entry faces slightly south-southwest, and is four bays wide. The two leftmost bays consist of two sets of glass double-doors with a double-higher transom light overhead. The bay second from appropriate has a single set of glass double-doors set left. Emblazoned on the fascia overhead is the word &quotTICKETS&quot. Upon getting into this door, the visitor will see a will-call ticket booth right away to the correct (behind what would have been the other set of glass double-doors). The rightmost bay is brick to about three feet, and a ticket window above that. It, also, has a fascia emblazoned with &quotTICKETS&quot above it.

The third level of the fieldhouse on the south side has been extended outward slightly. A glass curtain wall echoes the curtain wall on the west façade. A sharply pitched gable-like structure juts out of the two leftmost bays. Beneath a moderate eave is a floor-to-ceiling glass wall framed in metal.

To the west of the new major entrance is a modest, one-story structure. A berm rises up to the windowsills. The roof is flat, and the façade is brown concrete masonry. A metal double-entry door is on its left.

A curving thin brick interior wall pierced by doors separates the entry places from the arena inside the fieldhouse. Bleachers rise almost to the window below the dome’s eaves, and the steel trusses of the interior and dome are exposed. The developing can seat 9,500.

The north wing addition in structure was designed by in 1969 by Berg-Grabow and Partners (the successor to Willson and Berg). It is most likely that the modest workplace jutting off the south entrance was built at this time as nicely. The northwestern fill-in structure and covered walkway to Shroyer Gym had been almost certainly constructed in 1973.

Quoting Smithsonian National Air and Space Museum | Lockheed Martin X-35B STOVL:

This aircraft is the initial X-35 ever constructed. It was initially the X-35A and was modified to include the lift-fan engine for testing of the STOVL concept. Among its numerous test records, this aircraft was the first in history to obtain a quick takeoff, level supersonic dash, and vertical landing in a single flight. It is also the very first aircraft to fly using a shaft-driven lift-fan propulsion program. The X-35B flight test system was a single of the shortest, most powerful in history, lasting from June 23, 2001 to August 6, 2001.

The lift-fan propulsion technique is now displayed next to the X-35B at the Steven F. Udvar-Hazy Center close to Dulles Airport.

On July 7, 2006, the production model F-35 was officially named F-35 Lightning II by T. Michael Moseley, Chief of Staff USAF.

Quoting Smithsonian National Air and Space Museum | Grumman A-6E Intruder:

The Navy’s expertise in the Korean War showed the need for a new extended-range strike aircraft with higher subsonic functionality at extremely low altitude–an aircraft that could penetrate enemy defenses and discover and destroy tiny targets in any climate. The Grumman A-6 Intruder was designed with these wants in mind. The Intruder very first flew in 1960 and was delivered to the Navy in 1963 and the Marine Corps in 1964.

The Navy accepted this airplane as an &quotA&quot model in 1968. It served under harsh combat situations in the skies more than Vietnam and is a veteran of the 1991 Desert Storm campaign, when it flew missions in the course of the initial 72 hours of the war. It has accumulated much more than 7,500 flying hours, more than 6,500 landings, 767 carrier landings, and 712 catapult launches.

Specifics, quoting from Smithsonian National Air and Space Museum | Curtiss P-40E Warhawk (Kittyhawk IA):

Regardless of whether known as the Warhawk, Tomahawk, or Kittyhawk, the Curtiss P-40 proved to be a productive, versatile fighter during the initial half of Globe War II. The shark-mouthed Tomahawks that Gen. Claire Chennault’s &quotFlying Tigers&quot flew in China against the Japanese remain among the most common airplanes of the war. P-40E pilot Lt. Boyd D. Wagner became the very first American ace of Planet War II when he shot down six Japanese aircraft in the Philippines in mid-December 1941.

Curtiss-Wright constructed this airplane as Model 87-A3 and delivered it to Canada as a Kittyhawk I in 1941. It served until 1946 in No. 111 Squadron, Royal Canadian Air Force. U.S. Air Force personnel at Andrews Air Force Base restored it in 1975 to represent an aircraft of the 75th Fighter Squadron, 23rd Fighter Group, 14th Air Force.

Specifics, quoting from Smithsonian National Air and Space Museum | Lockheed SR-71 Blackbird:

No reconnaissance aircraft in history has operated globally in much more hostile airspace or with such total impunity than the SR-71, the world’s fastest jet-propelled aircraft. The Blackbird’s efficiency and operational achievements placed it at the pinnacle of aviation technologies developments in the course of the Cold War.

This Blackbird accrued about two,800 hours of flight time throughout 24 years of active service with the U.S. Air Force. On its final flight, March six, 1990, Lt. Col. Ed Yielding and Lt. Col. Joseph Vida set a speed record by flying from Los Angeles to Washington, D.C., in 1 hour, four minutes, and 20 seconds, averaging three,418 kilometers (two,124 miles) per hour. At the flight’s conclusion, they landed at Washington-Dulles International Airport and turned the airplane more than to the Smithsonian.

Particulars, quoting from Smithsonian National Air and Space Museum | Vought F4U-1D Corsair:

By V-J Day, September two, 1945, Corsair pilots had amassed an 11:1 kill ratio against enemy aircraft. The aircraft’s distinctive inverted gull-wing design and style allowed ground clearance for the huge, 3-bladed Hamilton Regular Hydromatic propeller, which spanned much more than 4 meters (13 feet). The Pratt and Whitney R-2800 radial engine and Hydromatic propeller was the biggest and a single of the most strong engine-propeller combinations ever flown on a fighter aircraft.

Charles Lindbergh flew bombing missions in a Corsair with Marine Air Group 31 against Japanese strongholds in the Pacific in 1944. This airplane is painted in the colors and markings of the Corsair Sun Setter, a Marine close-help fighter assigned to the USS Essex in July 1944.

Hasegawa 1/72 Grumman F-11F-1 Tiger, extended nose, Blue Angel #1

Blue Angels Tigers have been the longest serving Tigers. Its a pretty tiny airplane but technologies was moving so speedily that supersonic in level flight, four X 20mm cannon, and in-flight refueling capability weren’t enough to make a Visual Flight Guidelines (VFR – ie not evening/all weather, no radar in the nose…) fighter extremely interesting to the Navy. For a complete redesign that was initially pitched as a derivative of the F9F Cougar/Panther, the TIger is a fairly neat piece of function.
But with Vought’s F8U-1 Crusader and McDonnell F3H-1 Demon carrying some radar and promising much more, along with much more internal volume for fuel, the Tiger was good, but not very great sufficient.
The massive fin and rudder had been direct final results of the F-100C crash that killed test pilot George Welch- North American doubled the size of the F-100D’s fin and rudder. Grumman revised their prototype really swiftly when word got back from Edwards AFB, where both the F9F-11 and F-one hundred had been getting tested. Soon the F9F-11 was the F-11F-1 and a really modern-sized fin and rudder graced every Tiger that flew. The Tiger was also region ruled from the onset – taking a lesson from the tough luck of the Lockheed YP-90 and Convair YF-102, which looked great but could not get past the drag boost of the &quotsound barrier&quot.
It all seems so incredible, Vought, Lockheed, Grumman, North American, McDonnell, Convair, not to overlook Douglas, Republic, (and dark-horses Northrup, Boeing and Martin) all creating single-seat jet fighters in the USA, although AVRO Canada was conceiving the CF-105 to follow the CF-100s. AVRO, de Havilland, Bristol, Hawker, Supermarine (and other individuals?) have been designing single-seat fighters in the UK NORD and Dassault were lighting up French skies, and Bill Lear Jr was leading the design and style of an indigenous *Swiss* single seat jet. MiG, Yak, Sukoi and Tupolev had been all at it in the Soviet Union also.
Jet engine power and economy were nothing like today- they were heavy, weak, and blew fuel out the tail-pipe as if it expense

An Odd Sense of Tidiness?

Image by Alan Stanton
Beer can on the railings of Chestnuts Park. 30 January 2013.

Our buddy Lix Ixer and I have attempted to envision what may well be in people’s minds when they litter. Especially when an individual seems to take slightly more care than just dropping or tossing away a drink can.

On Harringay Online internet site Liz recommended a list of nine &quottypes&quot of litterers. Study the full version here. The drink-can spiker may belong to Liz’s very first variety.

Liz Ixer’s List of &quottypes&quot of litterers.

1 &quotThere is often an odd sense of ‘tidiness’ about some litterers: these are the ones who meticulously pop their cans and paper down the backs of utility cabinets, balance them on walls or tuck them down the side of planters. A small bit of them knows what they are performing is wrong and they hope by getting ‘tidy’, they offend less (perhaps there is a distant memory of a mum or dad telling them to put it in the bin).&quot

two &quotFervent believers in the Haringey litter gods who should be propitiated with frequent offerings&quot.
3 &quotThose for whom littering is a civil liberties situation. You don’t have the right to inform them what to do with their lives, which includes what they do with their litter.&quot
four &quotSweet old ladies who cautiously sweep their front step and garden every single morning and then open the front gate and whoosh it all into the street. &quot
5 &quotThe group who believe they are keeping men and women in employment by spreading the litter far and wide.&quot
six &quotThe bone idle litterer . . . who can see a litter bin within a stride but can not be arsed to go 1 step out of their way to deposit their waste.&quot
7 &quotCar diners . . . who park up, acquire a fast meals delicacy from the several fine establishments in the area, return to their automobile, fill up on grease and carbs then pile the packaging into the gutter prior to driving off.&quot
eight &quotThe litter deniers …. have two excuses for themselves: ‘my one particular bottle/can/wrapper will not hurt as there is a bag awaiting collection anyway’ or ‘I would use a bin but they are as well manky/complete/hard to use’,&quot
9 &quotThe inebriated. After six lagers for £5, I doubt you could see the bin, let alone navigate your way to it.&quot

The aim is that by by understanding people’s behaviour it may possibly be changed. &quotWe require&quot, says Liz Ixer, &quotto be far more inventive and inventive in how we get people to be far more accountable.&quot

Liz mentions past public education campaigns. Also some current initiatives. Examples incorporate: a lot more incentives for people to recycle decreasing the use of plastic bags higher engagement with little quick meals outlets to assist clean up and with businesses to decrease packaging.

.ten a gallon, which it most likely did. But they went faster the propeller engines. Compare the subterfuge and trickery all of these airframe firms of the 1950s were applying to the jet fighters of right now – tail surfaces are are nonetheless sharply swept, but wings got a lot straighter, since yet another ton or two of thrust is easier to make than a thin, tapering, swept structure that is stiff enough to do the job and cheap adequate to construct.
But the F11F or MiG-19, F-one hundred, F-8 Crusader, even the F-4 Phantom look like they’re going twice the speed of an F/A-18 or even the supercruise-capable F-22. (Supersonic without having afterburner).
